Extracellular accumulation of Aβ in β-amyloid plaques is thought to be associated with the neurodegeneration observed in Alzheimer’s disease (AD) patients, although a lack of correlation with cognitive decline raised doubts on this hypothesis. In different transgenic mouse models Aβ accumulates inside the cells and mice develop behavioral deficits well before visible extracellular β-amyloid accumulation. Here we show that intracellular Aβ accumulates in flotillin-1 positive endocytic vesicles. We also demonstrate that flotillin-1 is not only associated with intracellular Aβ in transgenic mice but also with extracellular β-amyloid plaques in AD patient brain sections. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
